String line = "101@ext-local       : SIP/101,CustomPresen  State:Idle            Presence:not_set         Watchers  0";
System.out.println(line.replaceAll("^(\\w+/\\d+)","")); <- не работает

    你需要Matcher#find()：

    String line = "101@ext-local       : SIP/101,CustomPresen  State:Idle            Presence:not_set         Watchers  0";
Pattern pattern = Pattern.compile("\\p{L}+/\\d+");
Matcher matcher = pattern.matcher(line);
while (matcher.find()) {
    System.out.println(matcher.group());
}
